SIGNALING APPARATUS.

3LECIFIOATION forming part of Letters Patent No. 474,852, dated May 17, 1892.

Application filed September 1'7, 1889. Serial No. 324,180. (No model.)

To all whom it may concern.-

Be it known that I, BERNICE J. NOYES, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Signaling Apparatus, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

In United States Patents Nos. 359,686 and 359,687, granted to me,a signaling apparatus is shown comprising signal-transmitters and a signal-receiving station connected by an electric circuit, the receiving-station containing a register-and an audible alarm, the latter responding to some signals and not to others. To effect this distinction, a circuit-changer is connected with the signal-transmitters,which is operated, in conjunction with the special signals, to out in, include, or render inoperative the said audible alarm.

In accordance with this invention several signaltransmitters are connected by an electric circuit with a receiving-station containing a register and a bell or other indicating instrument,thelatter being normallyincluded in the circuit, and a switch is also located at the receiving-station, which is moved by a distinguishing impulse to cut out or discon nect said bell for some signals and not othersviz., on the patrol-signals. As herein represented, the switch at the receivingstation is moved by aground impulse produced by closing a ground tap or branch at one of the signal-boxes in the line, said ground-tap being closed by means of the pointer or some other movable member within the box, although other distinguishing impulses may be produced and employed to effect this same result, as shown in a companion case filed concurrently with this, Serial No. 324,181.

The drawing shows in diagram an electric circuit containing signaltransmitters and inupon one or another pen and throw it into contact with one or another wheel. A pointer p is fixed to said selecting-cylinder, by which it is revolved, said pointer moving over a dial having marked thereon the signals corresponding to the circuit-wheels. The shaft b is rotated by a motor (not shown) of any usual construction. A circuit-changer is provided in each box, one member of which, as cl, is secured to a movable part of the apparatus, (herein shown as secured to the signal-selecting cylinder 0,) the stationary member or part, or it may be members or parts, d of said circuit-changer being included in a ground tap or branch e. The member d has an insulated spot (Z on it, so that when in some positions the ground tap or branch is closed and when in other positions it will be opened, and, as represented, it is closed on the patrol or post signals and opened on the special signalsas, for instance, wagon, telephone, and the like.

At the receiving-station a message-receiving instrument 1% is placed,which is herein shown as operatively connected with the signalingcircuit; but being included in a local circuit 'in it is governed by the armature of a relay m included directly in the signaling-circuit, although it is obvious that the message-receiving instrument or register m may be included directly in the signaling-circuit, if desired. A hell it isalso located at the signalreceiving station,it being herein represented as included directly in the signaling-circuit, although it may beincluded,like the register on, in a local circuit controlled by a relay, which will be included in the main circuit. A shunt-wire 0 is arranged around the coil of said bell, governed by the armature 0 of an electro-magnet 0 included in a ground tan or branch 0 leading from the signaling-circuit a.

WVith the signal-selecting cylinder arranged as shown the ground tap or branch at the signal-box isopen, and hence any signal transmitted will be received on the register and will also ring the hell; but if the pointer be turned onto a patrol-signal the ground tap or branch 3 will be closed, thereby attracting the armature o of the electro-magnet 0 and any interruptions in the signaling-circuit at such time at one side of the ground-tap 6 Will affect the register 02, but will not affect the bell, because the armature 0 will be held down by the magnet 0 as a closed groundcircuitis continuously formed. It willthus be seen that the belln will respond to all signals unless positively shunted out ordi'sconnected, and such positive action, While being herein shown as produced by an impulse different from the regular signaling impulse, yet -I do not desire to limit myself to any particular means for effecting such distinction.

I claim 1. lnan'electric circuit, a signal-receiving station containing a register and a bell op'er atively'con-neo'ted with the said circuit and responsive to the signal impulses,a controlling device forren'dering said bell non-responsive, and an elcc'tro-niagnet controlling the action of said controlling device and responsive toa distinguishing impulse, combined with a signal tra'nsmitter, also connected in saidcircuit and-contained in a box, and acircuit-cha'nger for transmitting the said distinguishing impulse to effect the operation of said electromagne't, substantially as described.

2. Inan electric circuit, a signal-receiving station containing a register and a bell oper-' atively connected with the said circuit and responsive to the signal impulses, a shuntling device for rendering said bell non-responsive, and an electro-magnet in another circuit controlling the action of said controlling de vice and responsive to a distinguishing impulse,combined With a signal-transmitter, also connected in said circuit and contained in a box for transmitting the signals, and a circuitchanger in another circuit for transmitting the said distinguishing impulse to effect the operation of said electro-magnet, substantially as described.

In testimony whereof I have signed my name to thisspecification in the presence of two subscribing witnesses.
